How Gold Is Mined Gold Mining Process World Gold Council

Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly. On average, it takes between 10-20 years before a gold mine is even ready to

Gold Processing Mining And Concentrating Britannica

The most common method is to roast gold-bearing minerals at temperatures of 450 to 750 C (840 to 1,380 F) to destroy the interfering sulfides. Oxidation can also be accomplished by the use of high-pressure reactors called autoclaves , in which the minerals in an aqueous slurry are treated at high temperature and pressure with oxygen-bearing gases.
